Description

Technical Field

[0001] The utility model relates to the technical field of oxide scale collection systems, in particular to an automatic oxide scale collection system for pre-treatment of drawn steel wires. Background Art

[0002] The wire rod used for drawing steel wire has a layer of oxide scale on its surface, the main component of which is a mixture of Fe2O3, Fe3O4, and FeO. The oxide scale is hard and brittle, and is not conducive to the subsequent drawing of the steel wire. Therefore, in the pretreatment stage of the wire rod, the oxide scale on the surface of the wire rod needs to be removed by means of physical bending and chemical corrosion. Usually, the descaling box bends the steel wire through the descaling wheel to make the oxide scale on the surface of the steel wire fall off, and the remaining oxide scale is removed by subsequent hydrochloric acid corrosion. The wire rod is passively released on the C-hook. Due to its own torsion and the obstruction of the C-hook, the dragged wire rod appears to swing in a large circle in front of the C-hook, causing the wire rod to swing freely and hit the rubber on the ground and the guardrails on both sides. The oxide scale will fall off before the wire rod enters the descaling box, which is also a way to remove the oxide scale, but this will cause a large amount of oxide scale to accumulate on the rubber skin on the ground. A large amount of oxide scale accumulation will cause the wire rod to hit the oxide scale when it is swung in a large circle, causing the accumulated oxide scale to be lifted up and turned into fine flying dust, which is not good for human health. It will also scratch the surface of the wire rod, which is not good for the subsequent processing process.

[0003] The Chinese utility model patent with application number 202321455185.6 discloses an oxide scale collection device, which is convenient for collecting oxide scale dropped from a single machine. However, the drawn steel wires are laid out in parallel and produced continuously. Each line is close to each other, and there is no extra space to install each large loop. In addition, the patent structure is complex, the investment cost is high, and maintenance is inconvenient.

[0004] Therefore, in the actual production process, the main treatment method is to regularly stop the entire large-scale production line and clean the oxide scale by people. This treatment method is not only primitive and wastes manpower and time, but also greatly affects the production efficiency of the production line. Utility Model Content

The power output ends of the motors 7 are connected to rollers, and the transmission belt 4 is connected between the two rollers.

[0032] Among them, the conveyor belt 4 is provided with staggered long scrapers and short partitions, and the long scrapers are in contact with the bottom of the trench 3.

[0033] The width of the conveyor belt 4 is slightly smaller than the width of the trench 3 .

[0034] Among them, the collecting basket 8 is not higher than the upper opening of the pit 2, and the conveyor belt 4 is not higher than the upper opening of the trench 3.

[0035] Among them, the pit 2 and the trench 3 are covered with steel plates.

[0036] The collecting basket 8 contains ton bags.

[0037] Embodiment 2: This embodiment is a further improvement of Embodiment 1. The main improvement is that when replacing the ton bag in Embodiment 1, the ton bag is easy to interfere with the conveyor belt 4; in this embodiment, the above defects can be avoided. Specifically:

[0038] A track 10 is installed in the pit 2, and the collecting basket 8 is placed on the track 10; the track 10 is a plurality of rollers arranged in parallel; in the present embodiment, the track 10 is installed in the pit 2, and when the ton bag is full of oxide scale, the collecting basket 8 is rolled from the place near the conveyor belt 4 to the other end through the track 10 to ensure that the ton bag will not be hindered by the conveyor belt when it is taken out, and the ton bag is lifted up with a lifting equipment and replaced with a new ton bag, and the collecting basket 8 is returned to the end near the conveyor belt 4.

[0039] Apart from this, this embodiment is exactly the same as Embodiment 1 and will not be described in detail here.

[0040] The specific working principle of the utility model is as follows:

[0041] During operation, the ground 1 at the bottom of the wire-laying channel is at a certain angle to the horizontal ground 1, the wire-laying end is high, and the ditch 3 is low. Under the impact of the wire rod, the guardrail rubber 5, and the ground rubber 6, the oxide scale falls off to the ground rubber 6. The fallen oxide scale is vibrated by the wire rod and the ground rubber 6 and moves in a downhill direction until it falls into the ditch 3. Most of the oxide scale will fall on the conveyor belt 4, and the other part will fall to the bottom of the ditch 3 through the gap between the conveyor belt 4 and the ditch 3. The conveyor belt 4 moves slowly under the drive of the motor 7 to transport the oxide scale on the conveyor belt 4 to the pit 2 on one side, and the oxide scale on the conveyor belt 4 A long scraper and a short partition are fixed. The long scraper can contact the ground 1 of the trench 3. With the movement of the conveyor belt 4, the oxide scale at the bottom of the trench 3 is scraped and sent to the pit 2 on the other side. A collection basket 8 is placed in the pit 2. The collection basket 8 is built with a ton bag. When the oxide scale is collected by the ton bag, the motor 7 is suspended to stop the conveyor belt 4, but the line is not released, and the production line continues to produce. The collection basket 8 is pulled from the place near the conveyor belt 4 to the other end through the rolling of the track 10 to ensure that the ton bag will not be hindered by the conveyor belt when it is taken out. The ton bag is lifted with a lifting equipment and replaced with a new ton bag, and the collection basket 8 is returned to the end near the conveyor belt 4, and the motor 7 is started. In daily production, the trench 3 and the pit 2 can be covered with steel plates. If the ton bag needs to be replaced or maintenance is required, the steel plate is opened for operation.
